We look at the division of 33870 by 12 
The aim is to understand the frequency of 12 in 33870.

Moving on to step 1:
12 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 12

Advancing to step 2:
The number 12 fits into 33 2 times, leaving a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 24 from 33 to get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 12

Going ahead to step 3:
If we divide 98 by 12, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
The remainder is 2 after subtracting 96 from 98.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 12

On to step 4:
If we divide 27 by 12, we get 2 and a remainder of 3.
The next digit of our result is 2. 
Result so far: 282.0
Subtract 24 from 27 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 12

Moving on to step 5:
12 goes into 30 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 2822.0
Deduct 24 from 30 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 6:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2822.5
Subtract 60 from 60 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2822.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 12 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2822.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 2822.5 with a remainder of 0.0.
